hadoop2.6.0(单节点)下Sqoop-1.4.6安装与配置(数据读取涉及hadoop、hbase和hive)

下载Sqoop

           http://sqoop.apache.org/

   或

           http://archive-primary.cloudera.com/cdh5/cdh/5/    (这个就是版本已经对应好了,不需去弄版本兼容问题了)

   或通过CM、Ambari

很多同行,也许都知道,对于我们大数据搭建而言,目前主流,分为Apache 和 Cloudera 和 Ambari。

     后两者我不多说,是公司必备和大多数高校科研环境所必须的!

     分别,详情见我如下的博客

环境准备

  Java

  Hadoop(Hdfs/Yarn)

 

 

 

 

 

 

Hadoop2.6.0(单节点)下安装Sqoop

  第一步:上传sqoop的安装包,这里不多赘述。

[hadoop@djt002 sqoop]$ pwd
/usr/local/sqoop
[hadoop@djt002 sqoop]$ ls

[hadoop@djt002 sqoop]$ mv sqoop-1.4.6.bin__hadoop-2.0.4-alpha/ sqoop-1.4.6
[hadoop@djt002 sqoop]$ ls
sqoop-1.4.6
[hadoop@djt002 sqoop]$ cd sqoop-1.4.6/
[hadoop@djt002 sqoop-1.4.6]$ pwd

bin CHANGELOG.txt conf ivy lib NOTICE.txt README.txt sqoop-patch-review.py src
build.xml COMPILING.txt docs ivy.xml LICENSE.txt pom-old.xml sqoop-1.4.6.jar sqoop-test-1.4.6.jar testdata
[hadoop@djt002 sqoop-1.4.6]$ cd conf/
[hadoop@djt002 conf]$ pwd
/usr/local/sqoop/sqoop-1.4.6/conf
[hadoop@djt002 conf]$ ls
oraoop-site-template.xml sqoop-env-template.cmd sqoop-env-template.sh sqoop-site-template.xml sqoop-site.xml
[hadoop@djt002 conf]$ cp sqoop-env-template.sh sqoop-env.sh
[hadoop@djt002 conf]$ vim sqoop-env.sh

 

 

 

 

 

   第二步:配置文件

[hadoop@djt002 conf]$ vim sqoop-env.sh

# included in all the hadoop scripts with source command
# should not be executable directly
# also should not be passed any arguments, since we need original $*

# Set Hadoop-specific environment variables here.

#Set path to where bin/hadoop is available
#export HADOOP_COMMON_HOME=    (建议都安装上)

#Set path to where hadoop-*-core.jar is available
#export HADOOP_MAPRED_HOME=     (建议都安装上)

#set the path to where bin/hbase is available  
#export HBASE_HOME=          (建议都安装上)

#Set the path to where bin/hive is available
#export HIVE_HOME=           (建议都安装上)

#Set the path for where zookeper config dir is
#export ZOOCFGDIR=            (因为,我这里是,hadoop-2.6.0的单节点分布,所以就没必要去配置Zookeeper了)

 

 

 

 

    如果数据读取不涉及hbase和hive,那么相关hbase和hive的配置可以不加;如果集群有独立的zookeeper集群,那么配置zookeeper,反之,不用配置。

在这里,我就全部配置吧,为了大家的方便!

 hadoop2.6.0(单节点)下Sqoop-1.4.6安装与配置(数据读取涉及hadoop、hbase和hive)_第5张图片

  所以,就没配置Zookeeper了。

复制代码
export HADOOP_COMMON_HOME=/usr/local/hadoop/hadoop-2.6.0

export HADOOP_MAPRED_HOME=/usr/local/hadoop/hadoop-2.6.0

export HBASE_HOME=/usr/local/hbase/hbase-1.2.3

export HIVE_HOME=/usr/local/hive/hive-1.0.0
复制代码

 

   

 

 

  第三:配置环境变量

hadoop2.6.0(单节点)下Sqoop-1.4.6安装与配置(数据读取涉及hadoop、hbase和hive)_第6张图片

#sqoop
export SQOOP_HOME=/usr/local/sqoop/sqoop-1.4.6
export PATH=$PATH:$SQOOP_HOME/bin

 

 

 

 

  第四步:生效环境变量

source /etc/profile

 

   

 

 

  第五步:这里大家,记得要给sqoop安装目录,授予权限给hadoop用户

chown -R hadoop:hadoop sqoop-1.4.6

 

 

 

 

  第六步:将相关的驱动 jar 包拷贝到 sqoop/lib 目录下。

   这里,省略了,很多,包括。hadoo的相关核心jar包、hive的相关核心jar包和hbase的相关核心jar包(补补)

 

 

 

 

 

 

 

 

 

 测试

   比如,我这里打开下,数据库

Navicat for MySQL之MySQL客户端的下载、安装和使用

个人推荐,比较好的MySQL客户端工具

 

   得,先启动之前安装好的数据库。

复制代码
[hadoop@djt002 ~]$ su root
Password: 
[root@djt002 hadoop]# cd /usr/local/
[root@djt002 local]# pwd
/usr/local
[root@djt002 local]# service mysqld start

[root@djt002 local]# 
复制代码

 

  然后,这边,选择连接。

复制代码

 

   然后,继续,还没达到我们想要的目的效果。

继续,怎么做呢?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

补充Sqoop命令怎么用?

待整理,如下,暂时不要去看

 

 

 

二、Hadoop2.6.0下安装Sqoop

   我这里,暂时,以Ubuntu环境下。

     步骤一: 下载sqoop2安装包:

http://mirrors.hust.edu.cn/apache/sqoop/1.99.6/   或者   http://archive.apache.org/dist/sqoop/   (推荐这个)

hadoop2.6.0(单节点)下Sqoop-1.4.6安装与配置(数据读取涉及hadoop、hbase和hive)_第16张图片

hadoop2.6.0(单节点)下Sqoop-1.4.6安装与配置(数据读取涉及hadoop、hbase和hive)_第17张图片

   我一般,传到Linux里的目录是,/usr/local/sqoop,这个,自行去设置。

步骤二、解压安装包,sudo  tar  -zxvf  sqoop-1.99.6-bin-hadoop200.tar.gz

步骤三、修改文件的名字为sqoop1996 ,

           sudo  mv  sqoop-1.99.6-bin-hadoop200.tar.gz     sqoop-1.99.6

步骤四、进入sqoop-1.99.6文件,进行配置:cd sqoop-1.99.6

  1.配置环境变量,sudo gedit ~/.bashrc,写入sqoop的安装路径和path变量

        export SQOOP2_HOME=/usr/local/sqoop/sqoop-1.99.6

               export PATH=.:$SQOOP2_HOME/bin:$PATH

               export CALALINA_BASE=$SQOOP2_HOME/server

        2.把MySQL的connect包拷贝到sqoop1.99.6/server/lib下面

   3.修改配置文件$SQOOP2_HOME/server/conf/sqoop.properties

   修改配置文件$SQOOP2_HOME/server/conf/catalina.properties,如图红框部分修改为自己的安装目录

 步骤五、启动sqoop server

  在sqoop的安装目录下,执行bin/sqoop.sh server start

 

步骤六、启动sqoop client

  在sqoop的安装目录下,执行bin/sqoop.sh client start
